The philosophy of cognitive science covers all philosophical topics pertaining to the scientific study of cognition. Its subtopics can be divided in four main ways. First, by the disciplines studying cognition: psychology, neuroscience, artificial intelligence, linguistics, etc.; this is the primary way in which the PhilPapers is currently organized. Second, by topic in the philosophy of science: explanation, reduction, etc. Third, by topic specific to the study of cognition: mental representation, computation, embodiment, consciousness, etc. Fourth, by the area of cognition under discussion: perception, motor control, language, reasoning, consciousness, etc. The philosophy of cognitive science overlaps with the philosophy of mind.
